IBM z Systems Virtualization Technologies
IBM z Systems offers three virtualization technologies:
The PR/SM-hypervisor allows for partitioning of the physical hardware in multiple logical partitions ("LPAR's").
The z/VM-hypervisor provides multiple virtual "guest machines" either directly on IBM z Systems hardware or in a logical partition.
The KVM-hypervisor provides multiple virtual machines in a logical partition.
SAP in IBM z Systems Virtualized Environments
You can choose between multiple virtualization configurations when running the components of an SAP system in an IBM z Systems virtualized environment. The most common configuration is running the DB2 database on z/OS in a logical partition and running the application servers in multiple Linux-guests which either run on a z/VM-system or on KVM for IBM z Systems in another logical partition.
